Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1-3, a thrust wheel set used on a mining tracked vehicle comprises a first thrust wheel 1 and a tracked body 10, outer swing arms 2 are arranged on two sides of the first thrust wheel 1, a spring fixing frame 3 is arranged at the top of each outer swing arm 2, a compression spring 4 is arranged on one side of each spring fixing frame 3, an inner swing arm 5 is arranged on the other side of each spring fixing frame 3, a connecting plate 6 is arranged on one side of each inner swing arm 5, a second thrust wheel 7 is arranged on the other side of each inner swing arm 5, a fixing bolt 8 is arranged between each spring fixing frame 3 and each compression spring 4, a flat gasket 9 is arranged on one side of each fixing bolt 8, and a tracked frame 11 is arranged on one side of the.

Furthermore, the two sides of the first supporting wheel 1 are rotatably connected with the two sides of the inner surface of the outer swing arm 2, and the top of the outer swing arm 2 is fixedly connected with the bottom of the spring fixing frame 3, so that the shock absorption can be realized by compressing the spring 4 during movement.

Furthermore, the other side of the bottom of the spring fixing frame 3 is fixedly connected with the top of the inner side swing arm 5, and one side of the connecting plate 6 is rotatably connected with the inner side swing arm 5, so that the spring fixing frame can be conveniently moved in a complex environment.

Furthermore, the two sides of the inner surface of the inner side swing arm 5 are rotatably connected with the two sides of the second supporting wheel 7, and the connecting plate 6 can be movably mounted with the track frame 11, so that the effect is better than that of the existing supporting wheel set.

Furthermore, the fixing bolt 8 is in sliding connection with the spring fixing frame 3, and the flat gasket 9 plays a role in preventing the fixing bolt 8 from falling off, so that the compression spring 4 plays a due role.
